Matrix.op_Equality Method

Determines whether the two specified Matrix structures are identical.

Namespace: System.Windows.Media
Assembly: WindowsBase (in windowsbase.dll)

public static bool operator == (
	Matrix matrix1,
	Matrix matrix2
You cannot use methods in XAML.



The first Matrix structure to compare.


The second Matrix structure to compare.

Return Value

true if matrix1 and matrix2 are identical; otherwise, false.


A Matrix stores its values as doubles. Because the value of a Double can lose precision when arithmetic operations are performed on it, a comparison between two Double structures that are logically equal might fail.

The following example shows how to check two Matrix structures for equality.

private void equalityExample()

    Matrix matrix1 = new Matrix(5, 10, 15, 20, 25, 30);
    Matrix matrix2 = new Matrix(5, 10, 15, 20, 25, 30);
    Boolean result;
    // result is true.
    result = (matrix1 == matrix2);            
    // result is false.
    result = (matrix1 != matrix2);
